Application December 6, 1950, Serial No. 199,531

2 Claims.

Many people find it difficult to raise a window sash from a closedposition to a raised position in which it is partially or entirelyopened, this being particularly true if it is a window which is of extrasize and weight or in case a radiator, kitchen sink, or the like, is infront of the window or in case the sash has become stuck due to dampnessor applied paint.

Therefore, it is one object of the invention to provide a lift or jackof such construction that it may be set at rest upon a window sill witha portion engaged in a finger-receiving socket of a sash and the jackthen tilted in a direction to force the sash upwardly towards its openedposition.

Another object of the invention is to provide a lifter or jack which isin the form of a lever having a claw at its front end for engaging inthe finger-receiving socket of the sash and in addition having thisfront or lower end portion of the lever provided with a fulcrum memberupon which it is rocked when in use.

Another object of the invention is to provide improved means forpivotally connecting the fulcrum member with the lever and in additionso form the fulcrum member that it may be selectively applied to thelever in such manner that the lifter may be accommodated to the distanceat which the finger-receiving sockets of the sash are spaced upwardlyfrom the window sill when the sash is in its lowered or closed position.

Another object .of the invention is to provide a lifting jack which maybe used for raising window sashes, as a tack puller, and for otherpurposes.

A practical embodiment of the invention is illustrated in theaccompanying drawing where- Figure l is a view showing the improved sashlifter in side elevation and applied in position for raising a windowsash, shown in vertical section,

Figure 2 is a view similar to Figure 1, showing the fulcrum memberdisposed in position for imparting added height to the lifter,

Figure 3 is a view showing the lifter with its fulcrum member removedand the lifter applied for use outwardly of the window,

Figure 4 is a view looking at the upper or front face of the lifter,

Figure 5 is a sectional view taken longitudinally through the lifteralong the line 5-5 of Figure 4, and

Figure 6 is a side elevation showing another manner in which the liftermay be used.

This improved lifter or jack is intended primarily as an implement forraising a window sash I which has become stuck in the window frame 2 2 ror is of such size and weight that it cannot be easily raised by merelythrusting the fingers of a persons hands in the finger-receiving sockets3 of the sash, but it will be understood that it is not limited to thisparticular use. By referring'to Figure 3, it will be seen that theimproved lifter may be used for raising a window sash equipped withfinger-receiving sockets of the type which project from the sash as wellas those which are countersunk in the sash. I a

The sash lifter consists of a lever 4, a claw 5, and a fulcrum member 6which is pivotally attached to the lever in rearwardly spaced relationto the front end thereof. The lever may be formed of wood, or othersuitable material, and is preferably rectangular in cross section inorder to provide it with flat side faces and front and rear faces. Thefront end of the lever is cut diagonally to provide it-with a front endface 1 which extends at anupward incline from the rear face of the leverto the front face thereof and the forward end portion of the front faceis formed with a recess 8 into which the rear portion of the claw 5 isfitted and firmly secured by rivets or pins 9 having heads at theirfront-and rear ends.-

The forward portion of the claw projects from the front end of the leverand formed with a notch or recess [0 which is V.-shaped, as shown inFigure 4, the fingers H of the claw having beveled surfaces I 2 alongtheir inner sides which border opposite sides of the notch It! in orderthat if it is desired to use the device for pulling tacks or nails, atack or nail may be readily engaged in the notch with its headoverlapping the fingers I I. It should also be noted that the portion ofthe claw projecting forwardly from the lever is bent upwardly somewhatso that when the claw is engaged under the head of a tack or nail, thelever may be rocked across this bend and then upon the rear edge of thefront end face 1 and the nail or tack easily pried out of wood intowhich it has been driven. This formation of the claw and its relation tothe front end of the lever also allows the claw to be easily forcedunder the lower edge of a window sash from a position outside the windowwith the bill and the sloping front end of the lever resting upon thewindow sill l2, as shown in Figure 3, the lever being then rocked acrossits front end so that the bill is swung upwardly and the sash raised asufficient distance for a person to slip his fingers under the sash andraise the sash. It will be observed that the fulcrum member is detachedfrom the lever during such use of the lifter.

The fulcrum member 6 is formed from a strand of stiff metal which isbent midway its ends to form an end bar [3 and side bars l4 extendingfrom opposite ends thereof, ends of the strand being bent inwardlytowards each other to form an end bar [5 at the opposite end of thefulcrum member from the end bar I3. The incompleted rectangular fulcrummember then has its side bars l4 bent closer to the end bar i3 than theend, bar l5 to provide end portions l6 and ll, the end portion I! beingof greater length than the end portion 16.

A clip I8 formed from a strip of resilient metal extends longitudinallyof the front end portion of the lever against the rear or under facethereof and is secured at its front end by the rear one I of the rivets9. The said under face of the lever is formed with a transverselyextending groove l9 and opposite this groove, the resilient stripforming the clip is bent to form an arched portion 20 merging into alongitudinally curved tongue or lip 2! Resiliency of the clip urges itslip towards the lever but allows it to be sprung away from the lever.Therefore, the fulcrum member may have a selected end bar disposedagainst the under face of the lever and then shifted forwardly until thesaid end bar moves between the clip and the lever and into the groove orseat 19 where it will be held by the clip. The fulcrum member will thusbe detachably and pivotally connected with the lever and serve totiltably mount the lever during use of the lifter.

Since the fulcrum member is detachably connected with the lever, it mayhave either its long end portion or its short end portion pivoted to thelever and thus have a selected end portion serve to tiltably mount thelever and its other end portion serve as a foot for resting upon awindow sill during use of the lifter. The lever may, therefore, betiltably supported at such a height that its bill may be fitted intoeither a finger-receiving socket mounted adjacent the lower edge of thesash, as shown in Figure 1, or the bill of the lever fitted into ahigher fingerreceiving socket, as shown in Figure 2. When the lifter isapplied outwardly of the window, the

fulcrum member may be easily removed, or, if there is room upon thewindow sill, the fulcrum member may be swung to the position shown inFigure 6 and the lever and the fulcrum member rocked upon the bends ofthe side bars while ments best adapted to perform the functions setforth, it is apparent that various changes in form, proportion and inthe minor details of construction may be resorted to without departingfrom the spirit or sacrificing any of the principles of the invention.

It will be seen from the foregoing description that I have provided acomparatively simple, inexpensive and efficient means for carrying outthe various objects of the invention.

Having thus described the invention, what is claimed is:

1. A window sash lifter comprising a lever, a claw extending forwardlyat the front end of said lever, a fulcrum member formed of metal andhaving side bars and end bars and having its side bars bent intermediatethe length of its side bars to form the fulcrum member with end portionsextending at right angles to each other, one of said end portions beinglonger than the other, and a clip carried by the front end portion ofthe lever at the underside thereof and including a resilient billextending longitudinally of the lever towards the rear end thereof andpassing across and frictionally gripping a selected end bar of saidfulcrum member and thereby pivotally mounting the fulcrum member withthe free end portion of the fulcrum member constituting a foot for thesaid fulcrum member.

2. A window sash lifter comprising a lever, a claw extending forwardlyfrom the front end of the lever, a fulcrum member formed of metal andhaving side bars and end bars and being bent intermediate the length ofits side bars to form end portions extending at right angles to eachother, one of said end portions being longer than the other, and a clipconsisting of a strip of resilient metal extending longitudinally of thefront end portion of said lever and secured at its front end to thelever, the rear portion of said resilient strip forming a bill for saidclip, said clip having its bill engaged across a selected end bar ofsaid fulcrum member and serving to detachably and pivotally connect thesaid fulcrum member with the lever, the attached end portion of saidfulcrum member serving to tiltably mount the lever and its free endportion constituting a foot for the fulcrum member.
